Lunch Break Video: When Sonny and Cher sang together one last time on the Letterman show

We know that part one of Cher’s memoir, set to be released in November, will include the story of how she met Sonny Bono and their road to stardom.

The year was 1987 and Cher was riding higher than ever with her movie career at its peak with Moonstruck out (she would later win the Oscars for best actress) and her first new album in six years Sonny, meanwhile, was running for mayor of Palm Springs (he would win and later be elected to the US Congress).

And for one special night on the NBC show Late Night With David Letterman, the former pop music and TV variety show duo reunited for a joint interview and (in the second video) then Cher is convinced to join Sonny to sing their first and biggest hit I Got You Babe which was number one on the charts in 1965.

Sadly, Sonny died a skiing accident in 1998.

Cher, still a top worldwide star, pays tribute to their music during a portion of her concerts and at 78 seems like she hasn’t aged a day.

Enjoy this wonderful trip down memory lane.
